Description

Technical Field

[0001] This application relates to the field of ceramic production technology, and more specifically, to an inkjet printer level tube anti-sedimentation device and an inkjet printing machine. Background Technology

[0002] In the production process of ceramic enterprises, there is an inkjet printing step, which involves using an inkjet printer to transfer designed textures and patterns onto the raw ceramic tiles. This process requires the inkjet printer to use inks of different colors or types, and these inks are stored in ink tanks.

[0003] During the production process, due to the large daily output of tiles, the amount of ink required is also large, and it needs to be replenished frequently. In order to more intuitively monitor the ink level in the ink tank, a liquid level tube is usually installed on the outside of the ink tank. The ink level can be known through the liquid level tube, and a corresponding program can be set so that the ink tank can automatically replenish or stop adding ink when the liquid level tube level is lower or higher than the set height.

[0004] As is well known, ceramic inkjet ink is composed of finely ground powder materials (including functional ceramic powders and pigments) combined with various solvents. After prolonged standing, the powder particles will aggregate and settle, resulting in ink sedimentation. Therefore, the ink must be shaken well before use. Similarly, during use, ink sedimentation can also occur at the bottom of the level tube due to prolonged standing. This sedimentation can clog the level tube, causing the ink level in the ink tank to drop asynchronously with the level in the level tube. In other words, the ink level control system cannot accurately determine the drop in the ink tank level. The inkjet printing problem is only discovered by the staff when the ink in the tank is completely used up. At this point, the staff needs to stop the inkjet printer, check the ink tank, clean the clogged level tube, refill the ink, and restart the machine. This not only wastes product and ink but also affects production continuity and increases the workload of the staff.

[0005] Therefore, existing technologies need to be improved. Utility Model Content

[0037] Example 1:

[0038] Please see Figure 1 This embodiment provides an inkjet printer level tube anti-settling device, which includes: an ink tank 100, a fluid delivery mechanism 200, and an ink recovery tank 300. The ink tank 100 is provided with a level tube 110. The fluid delivery mechanism 200 has an input end and an output end. The input end is connected to the level tube 110, and the ink recovery tank 300 is connected to the output end.

[0039] In this embodiment, the fluid delivery mechanism 200 is connected to the liquid level tube 110. The fluid delivery mechanism 200 can extract the ink from the liquid level tube 110, preventing ink from settling at the bottom of the liquid level tube 110. For example, the fluid delivery mechanism 200 can be electrically connected to a microcontroller. The microcontroller can stably realize the periodic start and stop of the fluid delivery mechanism 200, so that the fluid delivery mechanism 200 periodically extracts the ink from the liquid level tube 110 to the ink recovery tank 300, ensuring that the ink in the liquid level tube 110 does not settle or cause blockage, and that the liquid level tube 110 can accurately reflect the ink level in the ink tank 100. Furthermore, the ink recovered by the ink recovery tank 300 is not wasted. After a certain amount is recovered, it can be shaken and dispersed before being added back to the ink tank 100 for use. The microcontroller can be understood as existing technology, and its specific structure will not be described in detail.

[0040] Therefore, the inkjet printer level tube anti-settling device in this embodiment can be applied to existing inkjet printers. It is understood that existing inkjet printers have an ink tank 100 and a level tube 110. That is, a fluid delivery mechanism 200 and an ink recovery tank 300 can be added to the level tube 110, so that the fluid delivery mechanism 200 can periodically draw the ink in the level tube 110 to the ink recovery tank 300, ensuring that the ink in the level tube 110 will not settle and will not cause blockage.

[0041] For example, please see Figure 2 A liquid level sensor 111 can be installed on the liquid level tube 110. The liquid level sensor 111 is used to monitor the ink level in the liquid level tube 110. Three liquid level sensors 111 can be installed: the first liquid level sensor 111 is located at the bottom of the liquid level tube 110, the second liquid level sensor 111 is located in the middle of the liquid level tube 110, and the third liquid level sensor 111 is located at the top of the liquid level tube 110. When the ink level in the liquid level tube 110 reaches the position of the first liquid level sensor 111, the first liquid level sensor 111 sends an ink-adding signal. When the ink level in the liquid level tube 110 reaches the position of the third liquid level sensor 111, the third liquid level sensor 111 sends a stop ink-adding signal. The liquid level sensor 111 can be electrically connected to a microcontroller. When the fluid delivery mechanism 200 is working, the microcontroller can control the liquid level sensor 111 to stop sending warning signals, avoiding interference between the liquid level sensor 111 and the fluid delivery mechanism 200.

[0042] Therefore, in this embodiment, the fluid delivery mechanism 200 can periodically draw the ink in the liquid level tube 110 to the ink recovery tank 300, so that the ink in the liquid level tube 110 will not accumulate and will not cause blockage.

[0043] Specifically, please refer to Figure 2 The fluid delivery mechanism 200 includes a gear pump 210, a first conduit 220, and a second conduit 230. The gear pump 210 has an input end and an output end. The first conduit 220 is connected to the input end and the liquid level pipe 110, and the second conduit 230 is connected to the output end and the ink recovery tank 300.

[0044] In this embodiment, one end of the gear pump 210 is connected to the liquid level pipe 110 via the first conduit 220, and the other end of the gear pump 210 is connected to the ink recovery tank 300 via the second conduit 230. When the gear pump 210 is working, it can draw ink from the liquid level pipe 110 to the ink recovery tank 300, so that ink will not settle in the liquid level pipe 110 and there will be no blockage problem. The gear pump 210 relies on the sealed cavity formed by gear meshing to force the fluid to push, rather than relying on fluid momentum. It can provide a relatively stable flow rate even at high viscosity, has a strong ability to transport high viscosity fluids, stable flow output, simple and reliable structure, and is robust and durable.

[0045] The gear pump 210 can be understood as existing technology, and the specific structure of the gear pump 210 will not be described in detail.

[0046] It should be understood that the fluid delivery mechanism 200 is not limited to the gear pump 210 described above. Other fluid delivery mechanisms 200 may also be used, which are not limited here.

[0047] Specifically, please refer to Figure 2The first conduit 220 includes: a first vertical conduit 221, a first horizontal conduit 222, a second vertical conduit 223, and a second horizontal conduit 224. The first vertical conduit 221 is connected to the liquid level pipe 110. The first horizontal conduit 222 is connected to the end of the first vertical conduit 221 away from the liquid level pipe 110. The second vertical conduit 223 is connected to the end of the first horizontal conduit 222 away from the first vertical conduit 221. The second horizontal conduit 224 is connected to the second vertical conduit 223 and the input end.

[0048] In this embodiment, the input end of the gear pump 210 is connected to the liquid level pipe 110 in sequence via the second horizontal conduit 224, the second vertical conduit 223, the first horizontal conduit 222, and the first vertical conduit 221. The pipe layout is reasonable, avoiding the phenomenon of pipe confusion or entanglement.

[0049] Specifically, please refer to Figure 2 The height of the first horizontal conduit 222 is higher than the height of the liquid level tube 110. This can prevent the ink in the liquid level tube 110 from automatically flowing into the first horizontal conduit 222 and ensure that the first conduit 220 will not interfere with the liquid level tube 110.

[0050] Specifically, please refer to Figure 2 The fluid delivery mechanism 200 further includes a first fixing plate 240, which is used to mount the gear pump 210. In this embodiment, the first fixing plate 240 can be fixed on the frame of the inkjet printer. For example, the liquid level pipe 110 of the prior art inkjet printer is prone to ink deposition, which can easily cause blockage. In this case, the first fixing plate 240 can be set on the frame of the inkjet printer, and the gear pump 210 can be mounted on the first fixing plate 240. The gear pump 210 is connected to the liquid level pipe 110 and the ink recovery tank 300 through conduits. Then, the gear pump 210 can be periodically started and stopped by a microcontroller, so that the gear pump 210 periodically draws the ink in the liquid level pipe 110 to the ink recovery tank 300, ensuring that the ink in the liquid level pipe 110 does not deposit and does not cause blockage.

[0051] Specifically, please refer to Figure 2 The inkjet printer level tube anti-sedimentation device may also include: a filter 400, which is disposed between the fluid delivery mechanism 200 and the ink recovery tank 300.

[0052] In this embodiment, the filter 400 is used to filter the ink drawn by the fluid delivery mechanism 200, and the filtered ink then flows into the ink recovery tank 300. For example, the gear pump 210 can pump an appropriate amount of ink from the level tube 110 through the filter 400 into the ink recovery tank 300. After the filtered ink enters the ink recovery tank 300, once a certain amount has been recovered, it can be shaken and dispersed before being added back to the ink tank 100 for use, thus avoiding waste. It is understood that the filter 400 is prior art, and its specific structure will not be described in detail.

[0053] Specifically, please refer to Figure 2 The filter 400 is connected to the ink recovery tank 300 through the third conduit 410, and a valve 420 is provided on the third conduit 410.

[0054] In this embodiment, a valve 420 is provided on the third conduit 410. When the ink recovery tank 300 collects a certain amount, the valve 420 can be closed. Then, the ink in the ink recovery tank 300 is shaken and dispersed before being added to the ink tank 100. This can prevent the ink in the third conduit 410 or the filter 400 from dripping onto the ground.
